Higher reduction potential means

The reason for this becomes clear when we look at the standard reduction potentials (E°) and calculate the oxidation-reduction potential (ORP). The sum of the half reaction potentials, 0.76 and 0.34 V, gives an ORP of 1.10 V in standard conditions. Because 1.10 V is positive, this indicates that the reaction is favorable and occurs spontaneously.

Basically a signal is sent between them which determines your oxidation and reduction potential. The rate of electron transfer is measured in mV and read as ORP. The higher, the better, and most health departments in the United States recognize 650mV as the minimum acceptable ORP, and if you can get over 800mV that's great.The standard reduction potential is the likelihood of a particular molecule or atom to be reduced, or gain electrons. The standard reduction potential is expressed in volts at standard conditions ...constants or free energy changes for electrochemical half-reactions. In practice, the high reactivity of many species (e.g., organic radicals) participating in electrochemical reactions or the irreversibility or mechanistic complexity of redox reactions can make the direct experimental measurement of a corresponding reduction potential difficult.More the value of reduction potential, higher is the tendency to accept electron or electrons. Thus, oxidising nature increases from top to bottom in the electrochemical series. The strength of an oxidising agent increases as the value of reduction potential becomes more and more positive. F 2 (Fluorine) is a stronger oxidant than Cl 2, Br 2 ...The reduction potential for Ag + is more positive than that for Fe 2+.

On the other hand it could not oxidize chloride ions, Cl -, …To get the potential of the reverse reaction, known as an “oxidation potential”, simply reverse the sign of the potential. For example, standard oxidation potential for the half reaction of fluoride ions to elemental fluorine has a potential of -2.87 volts (which means it is very difficult to make this reaction occur). The reduction/oxidation (redox) condition of ground water affects the concentration, transport, and fate of many anthropogenic and natural contaminants. The redox state of a ground-water sample is defined by the dominant type of reduction/oxidation reaction, or redox process, occurring in the sample, as inferred from water-quality data.
